public static <E> ImmutableList<E> copyOf(java.util.Collection<? extends E> elements)

    Returns an immutable list containing the given elements, in order.
    Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
    Note that if list is a List<String>, then ImmutableList.copyOf(list) returns an ImmutableList<String> containing each of the strings in list, while ImmutableList.of(list)} returns an ImmutableList<List<String>> containing one element (the given list itself).
    This method is safe to use even when elements is a synchronized or concurrent collection that is currently being modified by another thread.
